Which is better for side sleepers?

The Rx is built for side sleepers and its plush surface cushions shoulders and hips. The Classic's Plush Soft is the closest match, but one side sleeper found it unsuitable after several months.

Which is better for back pain?

The Rx is the one designed for it, with Lumbar Zone quilting and a therapeutic support core. The Classic in Luxury Firm is a common choice for general back support but is not purpose-built for pain.

Is the Classic worth the savings over the Rx?

At $500 versus $1,295 as of November 8, 2026, the Classic costs far less and offers three firmness levels and a 365-night trial. The Rx only makes sense if you specifically need its plush pressure relief.

Both use recycled steel dual-coil cores and carry the same construction quality. The Classic's higher-density memory foam and wider firmness range make it the more durable pick for heavier sleepers.

Can I use either on an adjustable base?

Yes. The Rx lists an adjustable base as its foundation type. The Classic works with adjustable bases only at its 11.5-inch height.

Do both come with a sleep trial?

The Classic lists a 365-night trial. The Rx listing does not state one, so confirm the trial terms before buying.
